Adult stem cells and embryonic stem cells
Share this video:
In multicellular organisms , stem cells are undifferentiated or partially differentiated cells that can differentiate into various types of cells and proliferate indefinitely to produce more of the same stem cell. They are the earliest type of cell in a cell lineage. They are usually distinguished from progenitor cells , which cannot divide indefinitely, and precursor or blast cells, which are usually committed to differentiating into one cell type. In mammals , roughly 50— cells make up the inner cell mass during the blastocyst stage of embryonic development, around days 5— These have stem-cell capability. In vivo , they eventually differentiate into all of the body's cell types making them pluripotent.

Once an egg cell is fertilized by a sperm, it will divide and become an embryo. In the embryo, there are stem cells that are capable of becoming all of the various cell types of the human body. For research, scientists get embryos in two ways. Many couples conceive by the process of in vitro fertilization. In this process, a couple's sperm and eggs are fertilized in a culture dish. The eggs develop into embryos, which are then implanted in the female.

Difference Between Adult and Embryonic Stem Cells
Induced pluripotent stem cells or IPS cells just might be the most exciting development in the stem cell field over the last 15 years. They have unique potential for clinical impact for regenerative medicine too, both through their use to produce differentiated cellular therapies and indirectly via disease modeling as well as drug screening. The scientist who first made them, Dr.
